fix(ci): optimize docker integration tests with minimal compose

[noalimoy]

Summary

This PR optimizes the Docker Compose integration test workflow by replacing the heavy full-stack quickstart.sh deployment with a lightweight CI-specific configuration.

Fixes #777

Problem

The current workflow .github/workflows/integration-test-docker.yml relies on scripts/quickstart.sh, which triggers a full docker compose launch with 11+ services. This results in:

• Pulling many heavy container images from multiple remote registries
• No persistent Docker cache on GitHub-hosted runners (all images fetched every run)
• Frequent stalls or timeouts during docker pull
• Unstable and slow CI runs

Solution

Introduce a minimal docker-compose.ci.yml that strips nonessential services and replaces UI-based validation with simple curl health checks.

Changes

File	Change
deploy/docker-compose/docker-compose.ci.yml	New - Minimal CI compose with only 3 essential services
tools/make/docker.mk	Added CI-specific make targets
.github/workflows/integration-test-docker.yml	Updated to use CI compose instead of quickstart.sh

Before vs After

Before (Full Stack - 11+ services)

semantic-router, envoy, mock-vllm, jaeger, prometheus,
grafana, openwebui, chat-ui, pipelines, mongo,
llm-katan, dashboard (built from source)

• Timeout: 30 minutes
• Images: Multiple registries (Docker Hub + GHCR)
• Validation: UI-based tests

After (CI Minimal - 3 services)

semantic-router, envoy, llm-katan

• Timeout: 20 minutes
• Images: Primarily GHCR (2/3 services)
• Validation: Simple curl health checks

Removed Services (Not Needed for CI)

Service	Reason for Removal
grafana	UI monitoring - not needed for CI testing
prometheus	Metrics collection - not needed for CI
jaeger	Tracing - not needed for CI
openwebui	Chat UI - not needed for CI
chat-ui	Chat UI - not needed for CI
pipelines	UI pipelines - not needed for CI
mongo	Database for chat-ui - not needed for CI
dashboard	Admin UI - not needed for CI

New Make Targets

make docker-compose-up-ci      # Start minimal CI services
make docker-compose-down-ci    # Stop CI services
make docker-compose-logs-ci    # View logs
make docker-compose-ps-ci      # Check status

Test Results

✅ CI Workflow Passed: GitHub Actions Run #5

Test	Status
semantic-router health (localhost:8080/health)	✅ Pass
envoy proxy ready (localhost:19000/ready)	✅ Pass
llm-katan health (localhost:8002/health)	✅ Pass
Chat completions routing (localhost:8801/v1/chat/completions)	✅ Pass
Total Duration	~3 minutes

Testing

• Local testing with make docker-compose-up-ci
• All curl health checks pass
• Chat completions routing works end-to-end
• CI workflow passes on GitHub Actions
